Abstract

Um Arka area represents a portion of the Neoproterozoic Pan-African belt in the south Eastern Desert of Egypt. The present paper aims to investigate and evaluate the primary dispersion haloes of Au and associated elements. For this purpose, Au and associated elements have been determined in 105 quartz, dyke and country rock samples using both Inductively Coupled Plasma Optic Emission Spectrometry and Inductively Coupled Plasma Mass Spectrometry. Here, the statistical processing and mapping techniques of the analytical data have been applied. The results revealed that all the analyzed elements have been deviated from the normality, and there is a noticeable lack of correlation of both Au and Ag with As, Ba, Co, Cr, Cu, Fe, Ga, Hf, Hg, Mn, Mo, Nb, Ni, Pb, Rb, Sb, Sc, Sn, Sr, Th, Ti, U, V, Y, Zn, and Zr due to long history of Au mining activities. The primary dispersion patterns of Au, Ag, As, Hg and Sb referred to new sites of Au mineralization represented by the quartz veins, the country rocks, dykes, and tectonic zones. Moreover, Sn mineralization is expected to exist in the granitic rocks and Ni mineralization is expected to be in the metagabbroic rocks. Therefore, the area hosted three mineralized events involved Au-, Ni- and Sn- mineralizations that might be derived from a probable single major episode of mineralization sourced by hydrothermal solutions of Um Arka granitoid pluton. The primary dispersion patterns in the area were controlled by tectonic zones, lithology, and supergene processes. Finally, the Um Arka area is fruitful for Au-, Sn-, Ni- mineralization, and a promising target with success for the exploration project and starting new mining works.
